BOTH INTERNATIONAL & INLAND Which vessel must show forward and after masthead lights when making way?

A A 75-meter vessel restricted in her ability to maneuver
B A 45-meter vessel engaged in towing
C A 100-meter sailing vessel
D A 150-meter vessel engaged in fishing
AI Explanation

The correct answer is A) A 75-meter vessel restricted in her ability to maneuver. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel restricted in her ability to maneuver, regardless of length, must display forward and after masthead lights when underway and making way. This requirement is specified in Rule 27 of the COLREGS. The other options are incorrect because: B) A 45-meter vessel engaged in towing is required to display different light configurations, C) A 100-meter sailing vessel is not required to display forward and after masthead lights, and D) A 150-meter vessel engaged in fishing is also not required to display these specific lights.
